Analysis
As part of the City’s ongoing Capital Improvements Program, wastewater locations in decaying condition are recommended for replacement by the Water Utilities staff on a yearly basis. The City contracted with an engineering consultant, RPS Group, to prepare plans and specifications to replace aged wastewater mains in various locations throughout the city with new wastewater mains. For this design package, six (6) locations were identified.
On October 11, 2016, the City Council awarded this project to SYB Construction for the low bid amount of $2,604,696.50. Included as part of the contract award was a 5 percent contingency of $130,235.00 for project changes while under construction, which is typical for Capital Improvements projects. During construction near the intersection of Tarrant Road and NE 5th Street, the contractor discovered that a 15-inch wastewater line not in the scope of work for this project was in poor condition and in danger of a potential collapse due to corrosion of the existing pipe material. SYB Construction and immediately began investigating the condition of this 15-inch line and worked closely with RPS Group to decide upon a reasonable solution to repair the line as part of this project due to its poor condition. In order to repair the line in poor condition, an additional 546 linear feet of 18-inch wastewater line will have to be constructed by pipe bursting. This change order in the net amount of $177,970.09 provides for the additional 18-inch wastewater line to be constructed via pipe bursting, costs for investigation of the 15-inch line in poor condition referenced above, and quantity corrections for pipe rehabilitation and wastewater manholes.
City Staff recommends approval of Change Order Number 1, as this additional work performed by SYB Construction is necessary to keep the City’s wastewater collection system operational in this specific area of the city.
The revised overall project completion date for this construction contract is August 22, 2017.
